ABSTRACT:
A chucking device for removably holding a disk with a central opening, includes a shaft coaxially arranged with a specified center axis; a turntable fixed to the shaft, the turntable having a disk support surface for supporting the disk; and a resin-made cone arranged axially above the turntable, the cone including a shaft-fixed portion fixed to the shaft, a disk holding portion having an annular disk holding surface inclined radially outwardly and axially downwardly, and an arm portion for radially interconnecting the shaft-fixed portion and the disk holding portion. Herein, the arm portion includes a support portion extending radially outwardly from the shaft-fixed portion and an elastically deformable portion joined to the support portion for being elastically deformed to axially downwardly move the disk holding portion as the disk comes into contact with the disk holding portion.
